ORGANIC LIQUID OXYGENATOR Russian patent published in 2022 - IPC A61M1/16 A61M1/26 B01D63/02 

FIELD: medical equipment.

SUBSTANCE: invention relates to medical equipment, namely to an organic liquid oxygenator (1; 100). The oxygenator (1; 100) comprises a container body (2) with a longitudinal axis (A). The oxygenator (1; 100) has a first inlet (3) for oxygen and a second outlet (4) for the exhaust gas produced in the above container body (2). The oxygenator (1; 100) includes a third inlet (5) for the organic fluid medium subject to oxygenation and a fourth outlet (6) for the organic fluid medium subjected to oxygenation and produced in the above container body (2). The oxygenator (1; 100) has an oxygenation chamber (7) for the above fluid subject to oxygenation, located in the above container body (2). The oxygenator (1; 100) includes a distribution pre-chamber (17) for the fluid subject to oxygenation between the third inlet (5) and the above oxygenation chamber (7). The oxygenator (1; 100) has multiple capillary fibres (8), permeable to liquids and porous to gases, configured to cover said fibres with said organic liquids and secured by means of securing means (28) inside said oxygenation chamber (7) in accordance with a general parallel direction. The oxygenator (1; 100) comprises a dynamic distribution apparatus (24) supported in said distribution pre-chamber (17) by means of a bearing (20). Said set of capillary fibres (8) is collected into a package containing coils of adjacent layers (S) of fibres arranged transversely relative to said longitudinal axis (A) and located between at least two perforated flat plates (14, 15) located parallel to each other in said oxygenation chamber (7). Lining elements (11) are located between said layers (S). Said lining elements comprise sheets (11) of a double-sided adhesive material, completely enclosed in a plastic-polymer element or a so-called filling (28). At least a central cylindrical used section (Ω1) is located perpendicularly between said adjacent layers (S), coaxial with said longitudinal axis (A), configured for said organic fluid medium to pass through said section.

EFFECT: improvement of an organic liquid oxygenator preventing formation of blood clots and thrombi in the body, creation of an organic liquid oxygenator allowing for optimisation of suitable surfaces both for gas exchange and for passage of blood flows enveloping tangles of hollow fibres, creation of an organic liquid oxygenator allowing for even distribution of blood at the entrance to the oxygenator without inhibiting blood flows and causing subsequent congestion thereof, creation of an organic liquid oxygenator wherein the ratio between the overall dimensions and the oxidising capability is optimised, creation of an organic liquid oxygenator significantly reducing condensation at the ends of hollow fibres forming a gas exchange apparatus.
